Yes, seen it, and it's obviously the wrong thing to do or I'd be
getting the result I'm looking for. But I can't see the correct way
of doing it. I.e. I can't see any way of setting each element of the
list to a function with a different 'form' value without using some
'i' like variable in a
Hello,
Why the correlation between the random effects is negative?
library(coxme)
rats1 - coxme(Surv(time, status) ~ (1|litter), rats)
random.effects(rats1)[[1]] #one value for each of the 50 litters
print(rats1)
rats2 - lmekin(time ~ (1|litter), rats)
fixed.effects(rats2)
Thanks I was doing something similar in SAS. I was looping macro based on a
dataset containing the values:
data _null_;
set summary2;
mindat=put(datepart(mindate),date9.);
min_date='mindat_'|| trim(left(_n_));
put mindate= mindat= min_date=; /*check values in log*/
call symput
thank you for the help
So will the entire syntax appear as
bootmean(na.omit(banks$two),na.rm = TRUE, conf = 90,nrep = 1000)

Hello,
I am having trouble creating a (1000,3,201) array in R from a data set
created within the same script. My problem is that I want to take a matrix
that is 1000x603
(called landmat) and separate this into 201 separate (1000x3) matrices.
My problem is when I try to do particular

this worked
bootmean(na.omit(Xt$Y), conf = 90,nrep = 1000)

Re: Missing Values
Don't give it any. Instead of banks$two, use na.omit(banks$two).
actually this is what worked
bootmean(na.omit(X$Y), conf = 90,nrep = 1000)

Hi all, I just installed R on my Mac OS X machine and wanted to installed
tcl/tk. So, I installed tcl/tk from this page:
http://cran.r-project.org/bin/macosx/tools/
It gets placed in /usr/local dir.
and then I installed R.
Next, in R, I set the TCL_LIBRARY variable by saying
Hello,
Try the following.
Q_use_2 - split(Q_use, as.Date(Q_use$date))
SC_use_2 - split(SC_use, as.Date(SC_use$date))
lapply(seq_along(Q_use_2), function(i) cor(Q_use_2[[i]]$Q,
SC_use_2[[i]]$SC))
Hope this helps,

Hello,
You don't need the loop, it can be done with one much simpler instruction.
Since the number of rows is not important, the example uses a 10x603 matrix.
x - matrix(seq_len(10*603), ncol = 603)
y - array(x, dim = c(10, 3, 201)) # that's it
# See the first two
y[, , 1:2]
Hope this helps,
